IntroI was born in Eleftheroupolis, Greece. I obtained my 5-year diploma from the Department of Computer Engineering and Informatics, University of Patras, Greece and my PhD from the Department of Informatics, Aristotle University of Thessaloniki, Greece. Since 2009, I am an Assistant Professor with the Department of Informatics of Aristotle University.
ResearchMy current research interests span the fields of DATABASES and DATA MINING. In particular, I am interested in efficient query processing techniques in database systems (multidimensional data management, spatio-temporal data management), algorithms for mining massive graphs (dense subgraph discovery, frequent subgraphs, hidden graphs, probabilistic graphs), parallel and distributed techniques for massive data sets (MapReduce, Pregel) and data management and mining over data streams.
